CHANGE-MAKING DEVICE.

Application filed January 17, 1922. Serial No. 529,891.

To all whom it may concern.'

Be it known that I ANGEm PAPoULIAs, a citizen of the United tates, residing at Steubenville, in the county of Jefferson and State of Ohio, have invented certain new and useful Improvement in Change-Making Devices, of which the following is a specification.

This invention relates to change making devices for automatically delivering the correct change, thereby preventing error in the amount of-cash refunded where the difference between the purchase price, admission or the like, is less than the amount tendered.

A primary object of the invention is to provide a simple and practical machine of the character set forth which requires little or no calculation on the part of the operator to obtain the desired change, thereby making the invention especially useful to persons not thoroughly familiar with the value of coins to be given in change or, on the other hand, greatly assisting and insuring accuracy in change-making operations of any kind. That is to say, it is proposed to provide a machine having keys representing the amount of the purchase, and keys representing the amount tendered, so that it is only necessary for the operator to manipulate the amount purchased key and then the amount tendered key to receive the desired change.

A further ob'ect of the invention is to provide a release ey which will automatically release all of the amount purchased keys in case of error without in any way affecting the other instrumentalities of the device, thereby enabling the operator to depress the correct keys for the desired change-making operation.

lVith the above and other objects in view which will more readily appear as the nature of the invention is better understood, the same consists in the novel features of construction, combination and arrangement of parts hereinafter more fully described, illustrated andclaimed.

A preferred and practical embodiment of the invention is shown in the accompanying drawings, in whicht Figure l is a plan view of the top of the device;

Figure 2 is a front elevation;

Figure 3 is a vertical sectional view taken onthe line 3 3 of Figure l;

Figure 4 is a horizontal sectonal View taken on the line 4--4 of Figure 3.

Similar reference characters designalte'` the present inventionI/nay be housed or concealedby any special design or type of cover or casmg, a practical embodiment is shown in the accompanying drawings from which it will be observed that the casing 1 has the top 2 through which the stems of the various keys project, as will hereinafter more fully appear while the front side thereof may be provided wlth a coin magazine, designated generally as M, and having a transparent window 3 and .a hinged cover 4 for rendering the coin holders 5 accessible for filling.

At the lower end of the coin holders 5 suitable means 6 is provided for supporting the stack of coins arranged within the holder, while beneath the said holders a'suitable delivery chute 7 may be provided for the purpose of conveying the coins to be given in change to the deliver outlet 8. V

As the novel features o the present improvement are susceptible of embodiment in units for chan ng coins of various denominations, it will e apparent that a description of one unit will apply to the others since the structural features may be duplicated to any desired degree accordlng to the number of coins available to make the desired change values from the amount tendered.

Accordingly, by way of example the unit representing the twenty-five cent coin value may be coveniently utilized to illustrate the features of the present improvement. This unit is illustrated in Figures 3 and 4 of the drawings from which it will be observed that the same includes in its general organization a coin ejector A, a plunger bar B, and a selective ejector enaglng member C adapted to be controlled the lamount purchased key D in such a way that it will be inoperative upon the manlpulation of the amount tendered key E, as will hereinafter more fully appear. Also the unit includes a releasing device R which may effect the release of the amount purchased key D in event that an error has been made in its selection.

Referring first to the coin e'ector A, it will be observed that the same inciudes an ejector stem 8, slidably supported in a frame 9, and having the coin ej ecting end l0 thereof normally held retracted by a spring 1l while the end l2 thereof is arranged in the path of 60 the change making mechanism constituting l movement of the shiftable ejector engaging 20 that connects it with a control lever 21 member or hammer 13 pivotally connected as at 14 with the bar 15 of the plun er device B. This plunger bar 15 is slidaly arranged within a barrel or casing 16 and is provided with the upstanding abutment pins 17 and 18 which are guided in the slots 17a and 18 of the casing.

For the purpose of normally maintaining the hammer 13 in axial alinement with the plunger bar 15, it is depressed by a flat s ring 19 riveted or otherwise aixed to the plunger bar. As will be seen from Fi re may be readily depressed against the tension of the spring 32 but cannot turn or twist so that the latch end 35 will avoid the 'keeper end 36 of the detent.

The amount tendered key E is the primary actuator for the lunger bar 15. As may be observed from lligure 3 of the drawings the stem V39 of the key E is slidably guided in the top 2 of the casing and the guide 4() and carries at its intermediate portion a suitable abutment collar 41 adapted to engage with the-arm 42 of a crank lever 43 which is pivotally supported on the shaft 44.

3 theA pivot pin 14 connecting the coup ing\\'1`he other arm 45 of the lever 43 extends member and the bar is arranged in a horizontal plane so thatthe spring 19 normally maintains the coupling member in the valley of the forward cut-away end of the casing 16. The front end of the hammer 13 is ivotally engaged by the lower end of the ink ulcrumed upon the shaft 22 and having its end 23 adapted to be engaged by the collar 24 on the stem25 ofthe' amount purchased key D. For the purpose of tensioning the link 20 'and also holding the bar 15 in its retracted position,a spring 26 may be c onnect` ed with the intermediate portion of the link and a suitable spring support 27 This arrangement makes is possible to utilize a single spring for tensioning the parts associated with the lunger bar and the connections for controling the ejector engaging member or hammer 13.

Referring now to the amount purchased key D, it will be seen that stem 25 of this key is slidably guided in the ilange 28 of a guide bar G which may be common to all of the amount purchased keys throughout the machine and whose vertical wall 29 may be provided with guide slots 30 for insuring the proper movement of the levers 21. In order to yieldingly support the amount purchased key D the intermediate part of the stem 25 1s provided with an abutment `collar 31 adapted to be engaged by a spring 32 resting upon the top surfacel of a carrier bar 33 which may also be common to the several amount purchased keys of the device.

As shown in Figure 3 the lower end of the stem 25 is of substantially of U-shaped formation, one leg of the U constituting the holder for the spring 32,.while the opposite leg 34 is preferably provided with an odset latch end 35 for engaging with the keeper hook 36 of a spring pressed detent 37 pivotally supported' as at 38 and constituting a restraining device for holding the keys D depressed. In connection with the substantially U-shaped formation of the end of the stein 25 it will be vobserved that the opposite legs of the U-shaped portion have a relatively free sliding engagement with the openings 33a of the bar 33 so that the key downwardly and may be provided at its lower end with a roller 46 for engagement with the abutment 17 of all of the plunger bars 15 ofthe unit as may be seen from I* igure 4. Thus, when the amount tendered key E is depressed the roller 46 will slidably en gage the abutments 17 a-nd push the bars 15 forward. If the'hammer 13 connected with the bar is in line with the axis of the bar as'shown in full lines in Figure 3, the coin ejector 8 will be moved forward. On the other hand, if the hammer is raised, that is held in its elevated position, as shown by the dotted lines in Figure y3 due to the depression 'o'f the amount purchased key D, the forward movement of the bar 15 will be idle so faras the coin e'ector is concerned. The releasing device which permit-s of correcting the amount purchased lin case of error by releasing the amount purchased key D, which has been depressed inadvertently, may be common toall of the several units of the device. As shown in Fi ures 1 and '4, for example, this releasing evice consists of the release key R exposed at the top of the ca sing 1 and having its stem 47 adapted to engage with the arm 48 of a lever 49 which ispivotally supported as at 50, and has an arm 51 adapted to engage with a releasing bar- 52 which is common to all of the detents 37 of the several units of the device. Thus, if the amount purchased key D is depressed so that the end 35 of the stem portion of the key becomes engaged with the key end 36 of the detent through error, and it is desired to correct the. error, the releasing key R makes such correction possible upon its depression, because the arm 51 of the lever 48 will engage the common release bar 52 to thereby rock the detent 37 on its axis 38 and release the key D. That the key D will return to its normal position will be apparent because the spring 32 will expand and the spring 19 will pull @the hammer 13 downwardly as well as the link 20, thus causing the elevation of the end 23 of the lever 21.'

The release bar 52 being common .to thedetents of all of the units also serves the purpose of'disconnecting the end 35 from the keeper hook 36 of the detent when the plunger bar 15 moves forward on its operative stroke to actuate the coin e'ector. That is to say, as the bar 15 is move forward by the depression of the amount tendered key E through the connections already described` the abutment pin 18 of the bar 15 will ad- Vance and engage the release bar 52 and rock the detent to therebyl disconnect the arm 34 of the stem for the key D to permit it to be returned to normal position and be ready for the next operation.

In order to simplify the making of change by the operator it is proposed to have as many amount tendered keys as are necessary to make all change values within the given money limit of each unit, and in the case of certain purchases to deliver the change in ieces of money of the largest denomination. To that end, it is desirable to effect a combination of the operating instrumentalities associated'with several keys by the depression of a single amount purchased key.

For example in the twenty-five cent unit the pieces of money provided to make all change values for purchases under twentyfive cents are three five-cent pieces and one j ten-cent piece. Suppose a customer makes a fifteen cent purchase and tenders a twentyfive cent piece in payment. Instead of depressing the three five-cent keys individually to give the aggregate amount of the purchase, it is only necessary to depress the fifteen-cent key which will automatically carry all three of the live-cent keys and their operating connections into an inoperative position. That is to say, as may be observed from Figure 4, the fifteen cent key is not connected with any of the instrumentalities for directlyv actuating the coin ejector, but the stem 53 thereof is provided with an offset portion 54 carrying a combination depressing bar 55 which is common to all of the levers 21 of each of the five cent units. Therefore, upon the depression of the fifteen cent key the instrumentalities connected with all of the five cent units will be depressed at once, thereby elevating the coupling member 13 of each five cent unit, so that when the amount tendered key E indicating the twenty-five cent purchase is depressed, the forward movement of the bars 15 of each five cent unit will be idle, but the bar 15 of the ten cent unit will move forward so that its hammer 13 will engage with the end l2 of the coin ejector to thereby remove a single ten cent piece from the bottom of the stack of dimes in the ten Cent holder.

Obviously, amount purchased keys of other denominations, such for example as the twenty cent key, may be provided with a similar combination bar 55a, the same engaging the lever 21 of the ten cent unit and the levers 21 of the two adjacent live cent units. This arrangement may be duplicated lthroughout the machine at will to effect any eject only the difference between the amount purchased and-the amount tendered, which v represents the change due the patron.

n explanation of the provision of three 5 unit it is pointed out that this is done to give a dime and two nickels as the change from a 25 piece when a 5 purchase is made, or, on the other hand, to ive three nickels in change when a 10 purciliase is made and a 25 piece tendered in payment. Frequently occasion arises to have small pieces of change available, and the provision of the three 5 and the one 10 unit makes this possible.

It will also be apparent device may be constructed to utilize pennies as a part of the change combination, but since as a rule pennies are not desirable'in change, it is preferable to provide a separate penny change maker which may be conveniently placed at one end' of the machine as shown in Figures l and 2 of the drawings. This device may be of any desired form of construction and essentially includes a penny magazine 60 and an ejector 61 operating by key '62 for discharging the pennies from the magazine into the delivery chute 63.

It is believed that the operation of the device will beapparent from the foregoing description but for the purpose of illustrating a complete cycle ofl units, reference may be made to Figures 3 and 4 of the drawings which illustrate in detail the change making unit for a twentyfive cent tender. Figure 3 shows one ofthe five cent units and for example assume that a five cent purchase is made and a twentylive cent piece tendered in payment. In that case, the operator will depress one of the live cent keys D which will have the effect of causing stem 25 thereof to descend against the tension of the spring 32 and snap the latch end 35 of the stem beneath the keeper hook 36 of the detent 37. lVhen the key is thus depressed and held by the detent, the lever 21 having been engaged by the collar 24 of the stem is rocked to its dotted line position in Figure 3 thereby pulling the hammer 13 upwardly so that when the plunger bar 15 is thrown forward by the depression of the amount tendered key E, the end of the coupling member13 will avoid the end 12 of the coin ejector. However, it will be understood that the hammers 13 of the units associated with the other two five cent pieces and the ten cent piece will remain in alinement with the bar 15 and move the coin ejectors of the coin values referred to, thereby ejecting two nickels and a dime as the change due the patron from the transaction. In the event that the wrong amount purchased key has been depressed it may be readily released by manipulation of the release key R, as previously described.
